A longer dropper post is one of the best upgrades you can make to your bike. The award-winning OneUp Dropper Post is the longest travel dropper you can fit in your bike. Whether you’re an XS or XXL rider, we have the best post for you.

No other dropper can get your saddle lower. That’s because OneUp Droppers have the shortest stack height and shortest total length of any dropper post and the widest range of travel options (70-240mm). 

Available in 90mm, 120mm, 150mm, 180mm, 210mm, and 240mm travel. Every post can be shimmed down in travel by 10 or 20mm so you can dial in your perfect length. Bikes and riders come in all sizes, so do OneUp droppers.

To find the longest dropper post that will fit you and your bike use the handy
Dropper Post Length Selector Tool
